We're dividing 77414509 by 770 
The aim is to understand the frequency of 770 in 77414509.

Moving on to step 1:
The number 770 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 770

Moving on to step 2:
77 divided by 770 is 0 with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (4) from the dividend to 77 and continue with: 774 / 770

Going ahead to step 3:
774 divided by 770 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 770 from 774 to get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 770

Let's proceed to step 4:
770 can be fit into 41 0 times, resulting in a remainder of 41.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 41 to get 41.
Take the next digit (4) from the dividend and append it to 41, then repeat: 414 / 770

Going ahead to step 5:
414 divided by 770 is 0 with a remainder of 414.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 414 and we're left with 414.
Bring next digit (5) of the dividend behind the 414 and repeat the process: 4145 / 770

Step 6:
When dividing 4145 by 770, we get 5 with a remainder of 295.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
The remainder is 295 after subtracting 3850 from 4145.
Bring next digit (0) of the dividend behind the 295 and repeat the process: 2950 / 770

Let's proceed to step 7:
2950 divided by 770 is 3 with a remainder of 640.
Use 3 as the next digit of our solution. 
Result so far: 10053.0
Subtracting 2310 from 2950 leaves us with 640.
Grab the next digit (9) from the dividend, add it to 640, then carry on: 6409 / 770

Moving on to step 8:
770 goes into 6409 8 times with a remainder of 249.
The number 8 becomes the next digit in our result. 
Result so far: 100538.0
The remainder is 249 after subtracting 6160 from 6409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Going ahead to step 9:
2490 divided by 770 is 3 with a remainder of 180.
The next digit of our result is 3. 
Result so far: 100538.3
If we take 2310 away from 2490, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
When dividing 1800 by 770, we get 2 with a remainder of 260.
Record the quotient 2 as the next digit in the result. 
Result so far: 100538.32
If we subtract 1540 from 1800, we get 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Let's proceed to step 11:
770 can be fit into 2600 3 times, resulting in a remainder of 290.
Record the quotient 3 as the next digit in the result. 
Result so far: 100538.323
The remainder is 290 after subtracting 2310 from 2600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 12:
770 can be fit into 2900 3 times, resulting in a remainder of 590.
Record the quotient 3 as the next digit in the result. 
Result so far: 100538.3233
The remainder is 590 after subtracting 2310 from 2900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

After the division, we end up with 100538.3233 and a remainder of 0.0059.
